    简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 (! a;}V<7  
    2,'~'  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: me@k~!e"z  
    enableservice('AutomationServer', true) _*w kTI+j  
    enableservice('AutomationServer') ?uh%WN6nU]  
    <P@ "VwUX  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 Mh "iyDGA  
    P1_6:USBM  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: H"NBjVRU%  
    1. 在FRED脚本编辑界面找到参考. 7x=-1wbi  
    2. 找到Matlab Automation Server Type Library VW\xuP  
    3. 将名字改为MLAPP SDu%rr7sQ

    bt=z6*C>A  
    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 A=96N@m6

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ak_n  
    1. 创建Matlab服务器。 sW]>#e  
    2. 移动探测面对于前一聚焦面的位置。 M#}k@ ;L3  
    3. 在探测面追迹光线 ]?sw<D{  
    4. 在探测面计算照度 tS3!cO\  
    5. 使用PutWorkspaceData发送照度数据到Matlab 3w&Z:<  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 xey?.2K1A  
    7. 用Matlab画出照度数据 h9Tst)iRi  
    8. 在Matlab计算照度平均值 woUt*G@  
    9. 返回数据到FRED中 ZFC&&[%-sG
